Since there’s no ANC, battery life matches the Z.N.E. 01 ANC with 6 and 25 hours. This is an area where the Adidas give up a little time to the likes of the Jabra Elite 7 Pro and JBL Reflect Flow Pro. Like the Z.N.E, the figures bandied about are fine for gym use, but they’re just about okay if we’re talking about using them more often. The FWD-02 Sport are the third in a trio of true wireless buds from the Adidas and Zound Industries collaboration, with this model specifically aimed at runners. The lid is detachable to avoid breakages. This hasn’t been an issue for me with other earbuds, but perhaps it’s a concern for those who are a bit rougher with their earbuds and fling them into their gym bag. For extra features, Adidas also has a dedicated app which I used during my review of FWD-01. That app helps optimize audio, for the most part, but also delivers more accurate readouts for the battery level. And, best of all, the app includes customizations for the multi-function button attached to these earbuds.

Now, Adidas FWD-01 is part of the company’s “Running” line of wireless earbuds. And, as such, it isn’t necessarily the best option if you happen to need to put a lot of distance between yourself and your smartphone. In fact, compared to other earbuds I’ve had the opportunity to review, Adidas FWD-01 performed among the worst I’ve tested on range. The included USB-C charging cable is incredibly short. It connects to an uncovered port on the right earpiece. The earphones also ship with a cool mesh/neoprene carrying pouch. From our time using the FWD-01, the controls are satisfactory in terms of responsiveness. Using them isn’t a hassle either, which is good especially when you’re running and don’t want to fuss over the controls too much. The Transparency mode sounds natural enough, opening up the area around the user for more situational awareness of the goings-on at your sides and behind you. The mic offers strong intelligibility. Using the Voice Memos app on an iPhone 8, we could understand every word we recorded. The mic signal was strong and there was even some bass depth to the audio. There was a little bit of typical Bluetooth distortion around the edges, but nothing that did much to alter the clarity. Conclusions

Where do the new Adidas FWD-01 sport in-ear headphones come in, then? One of the sporting giant’s first forays into the audio market, the FWD-01 is clearly intended for athletes, fitness enthusiasts, and runners as its target audience.

Otherwise, the battery in Adidas FWD-01 lasts even longer than the company claimed. And that’s under conditions that would drain most devices over a far shorter period than is claimed. And that’s bearing in mind that conditions such as distance from a source device, volume, media type, and other factors drastically change battery life from user to user. I listened at 90-percent volume from a distance averaging 20-feet. So my use was more intensive than most users’ will be. Adidas estimates roughly 16 hours of battery life, but your results will vary with your volume levels. Performance The FWD-02 ditch the stem-based design of the Z.N.E 01 models for a circular shape and attachable wings. You get a five-strong wing-tip selection (including one wing-less design) and four different ear-tips, so there should be a size to suit any person’s ear. I’d say it’s worth experimenting with the accessories before your first run; it would have saved me an ill-fitting set of earbuds had I done so. The Adidas FWD-01 aren’t a subtle bit of kit. Chunky left and right buds with a spidery mesh pattern, they look like they’ve been through a Tough Mudder or three straight out of the box. They aim to offer fitness fanatics the ultimate set of collar earphones featuring a rugged sweat-proof design, more wing tip options than can easily be counted, and a marathon-length battery life.Furthermore, while its Bluetooth 5.0 connectivity is extremely stable with phones, it doesn’t pair well with laptops or desktops. This then limits its versatility quite considerably, which means users have to use a separate pair of headphones when taking this out to the office and gym on the same day. Water- and sweat-resistance come in at IPX5, matching the Z.N.E. 01 ANC, which makes them resistant to low pressure and sustained jets of water, while the case is splash-proof at IPX4. The case is an interesting piece of design, with a “breathable” mesh top; if the earphones become wet, it allows the water to evaporate through it (and it works).

Finally, Adidas includes a fold-to-close carry case. Adidas made that from a mesh material and even added a slot specifically for the charging cable. But it’s also small enough that the accessories just barely fit without being difficult to place inside. So, unlike many other companies’ included carry cases, this one from Adidas doesn’t take up much more extra room than the earbuds themselves would. In terms of the earbuds, those bear a hooked rubber design. With the silicone tip and wing being completely replaceable for differing ear sizes.The sound quality of the FWD-01 is excellent, with a deep range of sound, full, clean rich bass and can easily be customized within the app.
